If you live in Windows Hell during your workday, do yourself a favor. Install AutoHotKey. Then create a script and paste this:
;Remaps 'CMD S' to save
!s::
send !
sleep, 500
send f
sleep, 300
send s
Return
; Switches left control & alt keys
LCtrl::Alt
LAlt::Ctrl
LWin::LWin
Set that script to load when Windows does. You're welcome.
